Microstructural Characterisation of Fibre-Reinforced Composites
Author: John SummerscalesPublisher: Elsevier
ISBN: 1855737566
Category : Technology & Engineering
Languages : en
Pages : 337
Book Description
Over the last 50 years, great progress has been made in developing artificial fibre-reinforced composite materials, generally using filaments with microscopic diameters. A wide range of reinforcement forms, from random arrays to fully aligned, can be used for commercial applications, with the microstructure being a critical factor in realising the required properties in a material.This is the first up-to-date review of how to apply advanced microstructural characterisation techniques to fibre-reinforced composites. Each chapter is designed to offer both a stand-alone introduction to its topic and detailed referencing for follow-up research. With contributions from experts from around the world, the book will be an essential reference for materials scientists and research workers in industry and academia alike. Comprehensive and up-to-date review of the microstructural features of composites Covers a wide range of microstructure characterisation techniques

Book Description
In the industrial manufacturing of metals, the achievement of products featuring desired characteristics always requires the control of process parameters in order to obtain a suitable microstructure. The strict relationship among process parameters, microstructure, and mechanical properties is a matter of interest in different areas, such as foundry, plastic forming, sintering, welding, etc., and regards both well-established and innovative processes. Nowadays, circular economy and sustainable technological development are dominant paradigms and impose an optimized use of resources, a lower energetic impact of industrial processes and new tasks for materials and products. In this frame, this Special Issue covers a broad range of research works and contains research and review papers.
Fabrication of SiC/magnesium Alloy Composite Via Friction Stir Processing

Pages : 128
Book Description
"One of the most interesting improvements in the history of materials is composites manufacturing. Because of their ability to improve different mechanical properties of some metals, nanoparticles have been given much attention in the composites community. After the successful use and popularity of Friction Stir Welding (FSW) in many applications worldwide, its latest modification into Friction Stir Processing (FSP) has recently been given a considerable amount of attention. FSP can be considered today as one of the most successful alternatives for fabricating metal matrix composite. In this investigation, a Silicon Carbide (SiC)/magnesium alloy composite was fabricated using FSP. Different combinations of tool rotational and translational speeds (RS and TS) were used throughout the study. The effect of such combination on the thermal profile, micro-hardness, and microstructure was studied and compared. Furthermore, a Response-Surface Methodology was used to develop a model to predict the micro-hardness for FSPed specimens using different combinations of process parameters. FSP of Mg AZ 31B as well as Mg/SiC composite was successfully accomplished using different combinations of tool rotational and translational speeds. Micro-hardness results showed excellent agreement with both the thermal and microstructural analysis. Micro-hardness results of the Mg/SiC composite showed a significant amount of improvement. The developed micro-hardness model was very accurate in predicting the micro-hardness values."--Abstract.

Book Description
This book addresses the issue of designing the microstructure of fiber composite materials in order to obtain optimum performance. Besides the systematic treatment of conventional continuous and discontinuous fiber composites, the book also presents the state-of-the-art of the development of textile structural composites as well as the nonlinear elastic finite deformation theory of flexible composites. The author's experience during twenty years of research and teaching on composite materials is reflected in the broad spectrum of topics covered, including laminated composites, statistical strength theories of continuous fiber composites, short fiber composites, hybrid composites, two- and three-dimensional textile structural composites and flexible composites. This book provides the first comprehensive analysis and modeling of the thermo-mechanical behavior of fiber composites with these distinct microstructures. Overall, the inter-relationships among the processing, microstructures and properties of these materials are emphasized throughout the book. The book is intended as a text for graduate or advanced undergraduate students, but will also be an excellent reference for all materials scientists and engineers who are researching or working with these materials.

Book Description
Carbon fiber-reinforced silicon carbide matrix (C/SiC) composite is a ceramic matrixcomposite (CMC) that has considerable promise for use in high-temperature structuralapplications. In this thesis, systematic numerical studies including the prediction of elasticand thermal properties, analysis and optimization of stresses and simulation ofhigh-temperature oxidations are presented for the investigation of C/SiC composites.A strain energy method is firstly proposed for the prediction of the effective elastic constantsand coefficients of thermal expansion (CTEs) of 3D orthotropic composite materials. Thismethod derives the effective elastic tensors and CTEs by analyzing the relationship betweenthe strain energy of the microstructure and that of the homogenized equivalent model underspecific thermo-elastic boundary conditions. Different kinds of composites are tested tovalidate the model.Geometrical configurations of the representative volume cell (RVC) of 2-D woven and 3-Dbraided C/SiC composites are analyzed in details. The finite element models of 2-D wovenand 3-D braided C/SiC composites are then established and combined with the stain energymethod to evaluate the effective elastic constants and CTEs of these composites. Numericalresults obtained by the proposed model are then compared with the results measuredexperimentally.A global/local analysis strategy is developed for the determination of the detailed stresses inthe 2-D woven C/SiC composite structures. On the basis of the finite element analysis, theprocedure is carried out sequentially from the homogenized composite structure of themacro-scale (global model) to the parameterized detailed fiber tow model of the micro-scale(local model). The bridge between two scales is realized by mapping the global analysisresult as the boundary conditions of the local tow model. The stress results by global/localmethod are finally compared to those by conventional finite element analyses.Optimal design for minimizing thermal residual stress (TRS) in 1-D unidirectional C/SiCcomposites is studied. The finite element models of RVC of 1-D unidirectional C/SiCIIcomposites with multi-layer interfaces are generated and finite element analysis is realized todetermine the TRS distributions. An optimization scheme which combines a modifiedParticle Swarm Optimization (PSO) algorithm and the finite element analysis is used toreduce the TRS in the C/SiC composites by controlling the multi-layer interfaces thicknesses.A numerical model is finally developed to study the microstructure oxidation process and thedegradation of elastic properties of 2-D woven C/SiC composites exposed to air oxidizingenvironments at intermediate temperature (T
